CHARLES N. CHOATE, 0F WOODSTOCK, ONTARIO, CANADA, ASSIG-NOR TO FRED E. VAN ATTA, OF NORTHVILLE, MICHIGAN.

R0 OT-SHREDDER.

'b all whom it may concern:

Be it known that I, CHARLES N. Cnoarn, a subject of the King of Great Britain and Ireland, residing at Woodstock, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Root-Shredders, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates generally to shredders or cutters, and particularly to a device of this character for slicing vegetables or roots, the construction being such that the material may be cut into narrow strips or slices without pulping.

The invention consists in the general construction of the shredder, in the particular construction of the cutter or shredding device proper, in the peculiar arrangement and combination of parts, and in various details of construction as will be more fully hereinafter pointed out.

In the drawings,Figure 1 is a longitu dinal section through the shredder, showing the shredder proper or cutter in elevation; Fig 2 is a fragmentary perspective view of the device; Fig, 3 is a section taken on line rc-rc of Fig. 1; Fig. 4 is a front end view; and Fig. 5 is a detached sectional perspective view of one of the cutter blades or knives.

In the drawings thus briefly described, A represents a suitable support, in the form of a framework, upon which is mounted a hopper B, either inclined or formed with an inclined bottom for carrying the material to be shredded which is within the hopper to fall toward the cutter. The hopper comprises preferably a rear end section 0, sides 6, and a front 0 having its upper portion curved inwardly, as at (Z, over the sides and provided with a central discharge opening 0 therein.

Arranged within the hopper substantially midway of its ends is a transverse supporting bar C having a curved upper edge f and carrying upon its lower edge a shaft bearing g. The member described divides the hopper into two sections or parts, the rear of which is provided with a grated bottom D of concaved configuration, while within the forward section is mounted the cutting or shredding member E. The bars forming the concave bottom have their ends mounted within the rear end section a, and the forward ends within the transverse member C,

the engagement of the rods being along the upper curved edge of said member, as plainly shown in Fig. 2.

The cutter or shredder is frusto-conical in configuration, of a length to extend from the transverse member described to and preferably within the discharge opening 6 of the hopper, and is supported entirely upon a drive shaft f journaled in the bearing 9 and in a similar bearing 72, upon the lower edge of the end plate 0,. A hand-wheel G is mounted upon the shaft at the rear end of the hopper, and serves as the actuating device therefor.

The rotary cutter E comprises a head H rigidly attached to the shaft, a circumferentially fluted annulus I of greater diameter than the head, and a series of cutter blades J extending longitudinally between the parts and spaced circumferentially one from another, forming longitudinal openings through which the shredded material is adapted to pass within the cutter interior. The several blades described diverge from the head I-I, one edge of each blade is bev eled, and a series of notches, as K, are formed therein, and preferably spaced apart, as shown in Fig. 5, the spaces between the notches being preferably considerably greater than the width of the notches themselves, and the rear side of each notch is formed into a cutting edge 2'. The notches are so formed in the knives that they will bear a staggered relation in adjoining knives, the notches on one knife coming opposite to the spaces on the adjacent knife. The inner ends of the knives lie within recesses 7' formed in the head H, while the outer knife ends are preferably riveted or bolted to the fluted or corrugated ring or annulus E.

For guiding the material to be shredded to the cutter, I employ complementary guide plates L M, forming the hopper sides in the forward compartment and extending to the top of the cutter and downwardly along the under side in close proximity thereto, as indicated in Fig. 2. The guide plate L serves to conduct the roots to the opposite side of the cutter, while the plate M forms in connection with the cutter a wedge-shaped opening narrowing beneath the cutter. In this manner. the material is forced against the cutter, and upon rotation of the latter the sliced material passes within and is discharged from the open end of the cutter and without the hopper.

In operation, the roots, vegetables, or other materials to be shredded are placed within the hopper, the major portion of the dirt and other foreign material dropping through the grated opening. On rotation of the cutter the slicing is effected, and this without pulping, in the manner before pointed out, the shredded material being received within the cutter interior and eventually discharged through the forward end of the hopper.-

lVhat I claim as my invention is,

1. In a cutter or shredder, the combination with a support, of a hopper thereon, a transverse supporting member arranged within the hopper and dividing it into complementary sections, a grate bottom for one of the sections formed by a plurality of spaced members, each having their opposite ends secured respectively to one of the hopper ends and to the transverse support, a. main operating shaft journaled in bearings upon the transverse support and said hopper end, a hollow rotary cutter within the other compartment forming a part of the bottom thereof and supported and operated by the shaft, and a guide plate extending over one of the hopper sides to beneath the cutter to form with the latter a wedge-shaped opening.

2. In a cutter or shredder, the combination with a hopper, of a rotary cutter forming a part of the hopper bottom, guide plates upon opposite sides of the cutter diverging from the cutter to adjacent the plane of the cutter top, one of said plates extending beneath the cutter and forming therewith a wedge shaped opening.

In testimony whereof I aflix my signature in presence of two witnesses.
